Title: Taxonomic identification of pathogenic microorganisms and their toxic proteins
Inventor: POWERS LINDA S
IPC: G01N33/48
Filed: 2002-09-10
Abstract: The present invention describes a method for the binding of pathogenic microorganisms and their toxic proteins with ligands that have been covalently tethered at some distance from the surface of a substrate: distances of at least fifteen .ANG. are required for microorganism binding ligand tethers and at least six .ANG., are required for protein binding ligand tethers. The ligands described herein include heme compounds, siderophores, polysaccharides, and peptides specific for toxic proteins, outer membrane proteins and conjugated lipids. Non-binding components of the solution to be analyzed are separated from the bound fraction and binding is confirmed by detection of the analyte via microscopy, fluorescence, epifluorescence, luminescence, phosphorescence, radioactivity, or optical absorbance. By patterning numerous ligands in an array on a substrate surface it is possible to taxonomically identify the microorganism by analysis of the binding pattern of the sample to the array.

Abstract: Substrates have a hydrophobic surface coating comprised of the reaction products of a chlorosilyl group containing compound and an alkylsilane. Most preferably the substrate is glass. In one embodiment, highly durable hydrophobic coatings may be formed by forming a silicon oxide anchor layer or hybrid organo-silicon oxide anchor layer from a humidified reaction product of silicon tetrachloride or trichloromethylsilane, followed by the vapor-deposition of a chloroalkylsilane. Such a silicon oxide anchor layer will advantageously have a root mean square surface roughness of less than about 6.0 nm and a low haze value of less than about 3.0 %. Another embodiment includes the simultaneous humidified vapor deposition of a chlorosilyl group containing compound and a chloroalkylsilane. In preferred embodiments, the simultaneous vapor deposition onto a glass substrate of silicon tetrachloride and dimethyldichlorosilane results in a hydrophobic coating comprised of cross-linked polydimethylsiloxane, which may then be capped with a fluoroalkylsilane. The cross-linked polydimethylsiloxane layer may be formed on the surface of the glass substrate, or a silicon oxide anchor layer may be deposited under the cross-linked polydimethylsiloxane layer.

Title: Method of forming a sheet metal cup without a mandrel
Inventor: ROES JOHN P
IPC: B21D22/14
Filed: 2002-02-12
Abstract: The invention comprises a method of forming a sheet metal cup without using a mandrel. A cup shaped blank (10) is first produced having a relief (11) on a rim (12) or outer circumference. The blank (10) is clamped in the spinning machine. The relief (11) controls and facilitates the bending process, creating a uniform curve at a predetermined bending point. During the rolling process, a forming roller (20) is engaged with rim (12), and is moved progressively parallel with an axis of rotation (A-A). As the forming roller (20) moves, the rim (12) is progressively bent from an orientation normal to an axis of rotation to a position parallel to the axis of rotation. The fully formed rim (12) can then be punched to accommodate a bearing or shaft. This allows a small radius pulley to be formed without use of a mandrel.
